Sand baffle



When solenoid E is energized and chain 54 moved to 'turn spro'cket 55,- switch arm 58,

which'- is a spring, rides up the forwardly inclined surface ofswitch plate 61, and then, under sprin 'tcnsion, cdntacts with the surface 61, closing a circuit through the lamp N for illumirtating the personfor ob-' ject to be photographed. The movement of arm 58 tothe left from its position [shownin Figure '1 is very rapid. At the end of its movement to the left it. beingsprung,

passes the end of the contact plate 61 and moves backward onto a second plate. 62 on which plate it reverses its action and moves to the right/due to the action of weight 56.

The movement of the arm 58 to the rightis slow because of the action of the dash-pot 57 in retarding the downward movement of the weight. At the time arm 58 moves back ward upon contact plate 62, contact arm59 comes into contact with a contact plate 63*. and closes the circuit leading to motor 2. In the movement to the right of arm 58 of .plate 62 the lamp N continues to remain illuminatedand arm 59 remains 'on plate 63* for sufiicient time to enable such rotation of motor 2 as to rotate the cam 63 to such position that lever 64, arm 65 and weight 66 are lifted upwardly to cause the contact end of arm 64 to engage a contact plate 67 which serves to continue the circuit through the drive. motor.. a

As the cam continues to rotate, arm 64 I is permitted to falls Dash-pot 68 acting upon check-weight'69 serves to check the downward movement of the armso that the W arm does not leave contact 67 until the last exposure of the film whereupon the arm does leave contact 67 and, the motor 2 stops. A

second contact 67 is disposed in such position that its active face is not struck by arm 64 in its-upward movement, but is struck by the arm in its downward .movement. The contact of arm 64 with contact plate 67 closes a circuit through the solenoid 12 for eflecting the cutting operation during the rotation of the cam, a member C mounted thereon momentarily closes contacts A, A", and closes a circuit through magnet P. permitting the flow of liquid to the tank D' through tubes from a supply tank R, one

. of the tubes being indicated at 74.

, If. prior to the cutting operation upon an exposed strip of film, a previously exposed film passes through the machine in' completed form, and the timing mechanism shuts oli' the driving motor M, this will not affect the proper treatment of said exposed strip of film becausethe feeding and controlling means up to and including the cutting operation is independent of the feeding and controlling mechanism for the film subsequent to the cutting operation, and the movement of the elements in the cutting operation is employedrto throw into action the being motionless, film .is fed through the camera in accordance with the-timing of cam 63 and its associated parts until arm 64 leaves the camera motor contact 67 and shuts ofi current to the feed motor 2, the arm 64 continuing its dropping movement until it 'closes the circuit through contact 67* and the solenoid 12for performing the cutting operation. In the cutting operation rod 11 connected to the solenoid armature bridges contacts 38 and through the connections hereinbefore described starts the driving motor M and the timing control therefor. D f y If the second'or succeeding exposed strips of film follow a previously exposed strip into the tank D and thus-while the first strip is being developed and finished in said tank, the completion of the first strip and its discharge from the tank will not stop the tank feeding mechanism and the latter will remain in action until the last strip is fed through the tank forf-the reasons now to be until it snaps over upon contact 49-to energize magnets 36, 37, and thus release arm 24 so that it will Spring up to separate the contacts 28 in the circuit for motorM. Now

assume that a' .coin is placed in'the machine and tlie feeding mechanism of the film isstarted, this feeding mechanism continuing in action until the predetermined number of exposures have been made upon a strip and the strip is severed by knife 7. a In the action of solenoid 12.;to operate knife 7, rod 11 will be moved downwardly to operate pawl 23. .But arm 24 will be below" the range of pawl 23 so that the downward movement of the pawl will be inactive.

However, contact 39 will instantly bridge the contacts 38, and solenoid 36, 37 will be energized thus releasing the friction disks and. permitting spring 27 to move switch arm 24 toward the contacts 28 in'the circuit for motor M. However, these contacts will not be separated, because pawl 23 will lie in ,such position as to stop the complete movement of switch arm 24. I1 other words,

switch arm'24 will. move back to exactly the position where it is customarily moved bypawl 23 in separating the insulating knife 27. carried by the switch arm. from the contacts 28. Therefore, driving motor Mv will May 29, 1928. 1,671,589
